Perfecto
Bearings are good. But mind you not all of them are created equal. They are better than the ones in my video card. One of my old bearings makes horrible grinding noise. The rest hiss when spinning. Out of 10 new bearings, 7 are really quiet, 3 makes that same hiss noise. And one bearing of those 3 is much louder than the other 2. I just need 4 good ones. But if you need all of them quiet, think twice. But they all do the job without any problem.
